SHOCK-ABSORBER.

Specification of Letters Patent.

' Application led January 24, 1908. Serial No. 412,618.

vTo all whom it 'may concern:

l ication.

My invention relates to an improvement in a shock absorber for bicycles, motorcycles, or

It has for its object the provision of means for absorbing all jar While riding over rough streets or roads.

It has for its further object means for adjusting the tension of the absorber. l

In the drawings z-Figure 1 is a view of a bicycle with `the absorber attached; Fig. 2 is a detail view of the absorber on the front forks; Fig. 3 is a detail view of the absorber on. the rear forks, and Fig. 4 is a viewof a slight modification.

A, represents the bicycle frame having the forks B, B, and U-shaped arm C.

D re resents the front axle'and E the rear axle. igidly secured to the front forks are the links 1 consistin of two metal lates fastened to the forks y means of t e pins 2. Pivoted to the links 1 at 3 are links 4, which have an opening to receive the axle I). These links 4 also have the extensions 5, the pur ose of which will hereinafter be de- .scri ed.

6 and 7 represent metal bands, which are secured to the links 1 and 4 and form a spring between the same. The band 6 is secured to the links 1 by means of bolts 8 ada ted to enter perforations 9 in the ban The spring 7 is slotted at one end and is ada ted to it around the extension 5 on the lin 4. The ends are bent as shown and the band held in position on the link by means of a pin 10. The front end of the metal bands are held together by means of a thumb screw 11 and nut 12 and have a spacing block 13 therebetween.

The construction on the rear axle is slightly different as the link 14 is rigidly secured to sorber can readily be understood from the foregoing description. The parts being assembled cannot very easily get out of shape, and should the tension of the spring become inadequate to absorb all the shock, the same can be put under greater kor less'tension by simply turning the thumb screw 11. If this is not enough the arm 6 can be so adjusted to have the bolt 8 pass through any one of the perforations 9.

As shown in the modification, Fig. 4instead of having the spring made in two pieces I may make it 1n only one piece and adjust the same by means ofthe bolt Sand the perforations 9.

It is evident that slight changes might be resorted to in the form and arrangement of ing from the s irit and scope of my invention, and hence I o not wish to be limited to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. y In a shock absorber for bicycles the combination with a frame, of a link 'connected therewith, adapted to form a bearing for the axle, a s ring connected at one end to the frame ang at the opposite end to the link, and means for connecting the spring at different points throughout its length to the frame whereby to adjust the tension of the spring.

2. -A shock absorber for bicycles consisting of two links pivoted together at one end, one

of which is attached to the fork and the .point between the olt and thepivoted links.

3. A shock absorber for bicy es consisting of two links pivoted together, one of which is attached to the fork and the other forming a bearing for the axle, a two piece spring connecting the opposite ends of the links, one

iece of said spring being provided with perorations for adjustably securing it to the link on the fork and the other havinga slot adapted to engage the other link and looped ends .for receiving a pin for locking the spring in position.

4. A shock absorber for bicycles consisting of two links pivoted together at one end and connected at the opposite end by means of a 'the several parts described without departtwo-'piece spring, the forward ends of the spring being spaced by means of a block, and means for adjusting the tension of the spring.

5. A shock absorber for bicycles conslsting of two links pivoted together; one of which is attached to the fork and the other forming a. bearing for the axle, and e spring provided with a. plurality of perforstions connecting the ends of the links opposite their pivot7 and means for adjusting the tension of the I spring consisting of a bolt attached to one of seid links and adapted to register with any one of said perforatlons.

In testimony whereof I affix my signeture in presence of two Witnesses.

RAYMOND HUBER.
